TO ALL 'ro WHOM I MAY eononun:

Be itknown that I, NATHAN THOMPSGN, of1 5 Abbey Gardens, St. Johns Wood,in the county of Middle? sex, Englandl-a citizen of the United States of America, have invented or discovered new and useful Improvements in Means or Apparatus for Connecting together the Ends of Pipes or' Tubes, which improvements are also applicable for connecting together other articlcs;.and- I, the said NA'THAN THOMPSON, do hereby declare the nature of the said invention, and in what manner the some is to be performed, to be particularly described and ascertained in and by the following statement thereof; that is to say:

For this purpose the ends of the pipes or tubes are made or provided with flanges, and each flange, byv

preference, is partly surrounded by a portion of a short cylinder or socket, so that when the ends, of two pipes or tubes'are brought together in position for the connection to be ofiected, a more orless complete socket is formed. Between the ends of two pipes or tubes suitable washers or 'paekings are introduced, and in order to draw the two ends, and to hold thcmtightl together, the following means orapparatus is employed: Lugs, ears, or projections are fixed or formed on the end of one or of both the pipes or tubes, to which lugs, ears, or projections, cums, eccentrics, or locking-pieces are pinjointed orotherwise connected, with capability of turning upon a centre of motion; and I prefer to connect tuo of such cams, eccentrics, or locking pieees together, (one being on each side of -thejoi'nt,) thereby permitting offjhcir being simultaneously acted upon bye. lever connected or applied thereto, which lever, when the V0 pipes" tubes are securely connected together, lies close to the pipes or tubes; And inorder to prev ent the parts sieving when o'ifccfthe earns,'ecc'entricagor loclringg pieccshnrebeen acted upon to compress the washers or packings between the flanges to the-desired extent, I forin the noting or nipping parts of the cams, eccentrics, or locking-pieces somewhat on one side ci' their centres oi motion. Other suitable means, may, however, be employed to retain the levers end parts from moving, when once brought into their holding positions, until force is applied in the proper direction to rel'ease them from their holding. And inbrder that my invention may be more fully understood and readily carried into effect, I will proceed, aided by the accompanying drawings, more fully to describe the some.

Figure 1 is a sidc'view of the ends of two pipes or tubes, connected together according to my invention.

Figure 2 is u plan, end v Figure 8 is c sectional view, showing the parts in the position they would assume when the connection is completely effected. I

Figure 4 is a side view, and I Figure 5 is on end view of the end 0t one of the pipes or tubes, and

Figure 6 is a side view, and. I

Figure 'Tnn cnd-vicw of the end of the other pipe or tube, with ports applied thereto according to my invention.

a e are the ends of the two pipes to be connected together, E Z= are ilnng'es, which may be formed thereon or fixed thereto in any sui able manner, and e c are portions of cylinders connected to such flanges; ti! 0? are ear-lugs or projections connected to the flange b, and having cams, eccentrics, or locking pieces e e pin-jointed thereto, and, as shown in the drawings, I prefer to connect such coins, eeceutrics, or locking-pieces together in pairs, by means of a lever,f. One of each of suclrcums, eccentrics, er locking-pieces being on oppositc'sides of the pipe, suitable elastic or compressible washers or paekings, y, are employed between the. ends of the two pipes or tubes, and when the ports are placed in position, and the lcverfturuod so asto lie close to the pipe or tube, as shown in figs. 1, and 3, such washers or p-ackings are compressed between the ends of the pipes or tubes, and a secure joint is thereby made. In fig. 3 the lever f is shown by dotted lines, and in fig. 6 by full lines in the position it would ussunic preparatory to the sliding of the two fiangesb 7) upon each other in position for the connection to be made, It will lie seen by reference to the drawings that the nippingparts'ofthe cams, eccentrics, or locking-pieces are formed slightly at one side of their centres of motion, thereby tending, when thejoint is made, to retain the lcverf in its locked position; other suitable means may, however, be employed for this purpose. And in order that such nipping partsniaycontiuue to nip the flange during its entire mpvcmoot, I form inclines 5* on the flange 1' as shown, but I do not confine myself thereto, as the cams, eccentrics, or locking-pieces may be of a suitable form for this purpose. The portions of cylinder 0 e', when brought together, form an entire ring, and thereby eliectually enclose and protectthe washers orpnckings g from injury.

It will be readily understood that the inventionis equally applicable to all kinds of metal and other tubes, and may be cast on, or brazed, or soldered thereto, or the flanges, cylinders, and locking-pieces may be formed separatelyfrom such pipes or tubes, and the union thereof may be efiected by forming flanges on the pipes or tubes and cn'closing'tliem between the flanges of the connecting means, as will be readily understood, suitable washers or packings'being introduced between the parts. I would have it understood that althouglrI have shown only twocams, eccentrics, or locking-pieces a e in the drawing, other numbers of such cams, eccentrics, or lookingpieces may be employed, as will be readily understood, and they may, when more than two are employed, be acted upon separately.

Theinvention is particularly applicable to such pipes or tubes as require to be frequently and quickly connected or disconnected with each other, or with otherarticles, and I would have itjunderstood that although I have described the invention as applied to pipes or tubes, similar means may be employed for connecting together other articles, as will be readily understood.

Having thus described the nature of my invention, and the mode in which I carry the same into effect, I

would have it understood that I do not confine myself to the precise details herein shown and described, but 'what I do claim, is- I 1. The general combination and arrangement of parts for connecting together the ends of pipes or tubes, substantially as herein shown and described. I I 2. I claim the application of cams, eccentrics, or locking picces e e, or'equiva-lents therefor,substantially us and for the purpose herein shown and described; and

3. I claim the mode herein shown and described of operating upon such cams, eccentrics, or locking-pieces c e, by means of levers substantially as and for the purpose herein shown and described' NATHAN THOMPSON.
